The Cisco SG300-52 switch lets you extend highly secure network connectivity to guests in a variety of settings, such as a hotel, an office waiting room or any other area open to nonemployee users. Using powerful but easy-to-configure security and traffic segmentation capabilities, you can isolate your vital business traffic from guest services and keep guests' network sessions private from each other.
High Performance and Reliability
The Cisco SG300-52 switch is rigorously tested to deliver the high availability and performance you expect from a Cisco switch. The solution speeds up file transfer times and improves slow, sluggish networks, while keeping your vital business applications available and preventing costly downtime. As a managed switching solution, the Cisco SG300-52 also gives you the flexibility to manage and prioritize high-bandwidth traffic such as voice. That means you can empower your employees with state-of-the-art communication and productivity solutions, without draining the performance of your other business applications.
Fast, Easy Setup and Configuration
The Cisco SG300-52 switch is designed to be easy to use and managed by small businesses and the partners who serve them. The included device manager software provides an intuitive, web-based interface to simplify setup, security and quality of service (QoS) traffic prioritization, allowing even users without IT expertise to configure the switch in minutes. It also provides a Cisco FindIT Network Discovery Utility. This utility works through a simple toolbar on the user's web browser to discover Cisco devices in the network and display basic information, such as serial numbers and IP addresses, to aid in the configuration and deployment of Cisco Small Business products. The Cisco SG300-52 switch uses Cisco Discovery Protocol as well as Link Layer Discovery Protocol (LLDP-MED) to automatically detect all the devices connected to your network and then automatically configures them for the appropriate connectivity and instructs the devices to use appropriate voice VLAN or QoS parameters. For more advanced capabilities and hands-on control, the switch supports Smartport roles which configure the ports with specific levels of Security, QoS and availability according to the type of connected device, based on Cisco best practices and pretested configurations. The Auto Smartports feature applies the intelligence delivered through the Smartport roles and applies it automatically to the port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch deployments. Although the Cisco SG300-52 is designed to be deployed without using a command-line interface, Cisco Textview is available for those who prefer to use text-based configuration. Together, these features reduce the time your staff must devote to network deployment, management and troubleshooting.
Strong Security
The Cisco SG300-52 switch provides a high level of security and gives you fine-grained control to safeguard your network from unauthorized users. It's advanced security features include:
